[0016] The preferred embodiments of the present invention will be described in detail below so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0017] according to Figure 1 and Figure 2 A mounting base for a synchronous pulley includes a mounting base body on which a driven pulley 2 is mounted. The driven pulley 2 is connected to a driving pulley 1, which is equipped with a drive motor, via a synchronous belt 3. Since the driving pulley 1 needs to be connected to the drive motor, the mounting base is mounted on the driven pulley 2 to avoid structural complexity and maintenance trouble.

[0018] The mounting base body adopts an automatic tension adjustment structure, which can automatically adjust the tension and adjust it in time when the tension changes to avoid the phenomenon of skipping teeth.

[0019] The automatic tension adjustment structure includes a mounting structure for connecting the driven wheel 2 and a telescopic structure for adjusting the tension, wherein the mounting structure is mounted on the telescopic structure.

[0020] The mounting structure includes a central shaft 5, with baffles 6 symmetrically mounted on both sides of the central shaft 5. The driven wheel 2 is mounted on the central shaft 5 via bearings 4 and is in contact with the baffles 6 on both sides, so that the driven wheel 2 can rotate more smoothly.

[0021] The telescopic structure includes an installation strip 10, on the surface of which a groove 11 is formed. A slider 12 is installed in the groove 11. Sub-grooves 13 are provided on both sides of the groove 11. The sub-grooves 13 cooperate with the slider 12 so that the slider 12 will not disengage from the groove 11 when sliding.

[0022] The central shaft 5 has a threaded hole 8 in the middle, and the slider 12 has a threaded groove 9. The mounting structure is fixedly connected to the telescopic structure by screwing a bolt 7 through the threaded hole 8 into the threaded groove 9. The bolt 7 allows the mounting structure to be separated from the telescopic structure into two parts, making its production, maintenance and modification simpler.

[0023] An electric telescopic rod 14 is provided in the slide groove 11. The moving end of the electric telescopic rod 14 is connected to the left side of the slider 12, and the fixed end passes through the mounting strip 10 near the drive wheel 1 and is connected to the telescopic motor 15. The telescopic motor 15 is fixedly installed on the mounting strip 10. The electric telescopic rod 14 is used to drive the slider 12 to move, thereby adjusting the tension of the synchronous wheel.

[0024] A force monitoring module 16 is installed on the drive motor. The force monitoring module 16 is connected to an external control device via a wire. The control device inputs the required tension force parameters, and then the force monitoring module 16 controls the motor to adjust the extension and retraction of the electric telescopic rod 14 so that the tension force meets the set parameter requirements.

[0025] During installation, first install the drive wheel 1 and the driven wheel 2, bringing the telescopic motor 15 close to the drive wheel 1. Control the telescopic motor 15 via the control device to tighten the electric telescopic rod 14. Simultaneously, input the required tension parameters into the force monitoring module 16 via the control device. Then, install the synchronous belt 3. Finally, send a start signal to the telescopic motor 15 via the control device. At this point, the telescopic motor 15 operates, and the electric telescopic rod 14 extends. The force monitoring module 16 then monitors the telescopic motor 15. The tension force is equal to the resistance fed back to the telescopic motor 15 by the electric telescopic rod 14. The telescopic motor 15 shuts off when the resistance reaches the tension parameter value, and the electric telescopic rod 14 is then positioned.

[0026] If the force monitoring module 16 detects a change in tension during use, the telescopic motor 15 will restart according to the signal from the force monitoring module 16 and adjust the tension again, just like during installation.

[0027] Compared with the prior art, the present invention provides a mounting base for a synchronous pulley, which has an automatic tension adjustment structure, enabling automatic tension adjustment and timely adjustment when the tension changes, thus avoiding the phenomenon of tooth skipping.
